Liquid mixing device

ABSTRACT

An outer container has an inlet in one wall for admitting a first liquid into the outer container under pressure and an outlet in another wall for releasing liquid from the outer container. An inner container formed in the outer container has some walls in common with walls of the outer container and some walls in the outer container. The inner container has an inlet in a common wall for admitting a second liquid into the inner container and an outlet in a wall in the outer container for releasing the second liquid from the inner container into the outer container. A regulatable valve in the outlet of the inner container controls the volume of the second liquid released from the inner container into the outer container.

An inner container formed in the outer container hassome walls in common with walls of the outer container and some walls inthe outer container. The inner container has an inlet in a ".common wallfor admitting a second liquid into the inner container and an outlet ina wall in the outer container for releasing the second liquid from theinner container into the outer container. A regulatable valve in theoutlet of the inner container controls the volume of the second liquidreleased from the inner container into the outer container.

3 Claims, 2 Drawing Figures- III/[III LIQUID MIXING DEVICE DESCRIPTIONOF THE INVENTION The present invention relates to a liquid mixingdevice.

The principal object of the invention is to provide a new and improvedliquid mixing device which is of simple structure, but operates withefficiency, effectiveness and reliability. I

In order that the invention may be readily carried into effect, it willnow be described with reference to the accompanying drawing, wherein:

FIG. 1 is a perspective view of an embodiment of the liquid mixingdevice of the invention in use in mixing lawn water with lawn chemicals;and

FIG. 2 is a view, partly in section, of an embodiment of the liquidmixing device of the invention.

The liquid mixing device of the invention mixes a first liquid with asecond liquid. The first and second liquids may comprise any desiredliquids which are to be mixed. Thus, the first liquid may comprise, forexample, water, and the second liquid may comprise, for example, a lawnchemical solution such as, for example, fertilizer, weed killer,insecticide, or the like.

The liquid mixing device 1 of the invention comprises an outer container2, having walls 3, 4, 5 and 6 and other walls, not shown in the FIGS. Aninlet 7 is provided in the wall 3 for admitting a first liquid 8 intothe outer container 2 under pressure. An outlet 9 is provided in thewall 4 for releasing liquid from the outer container 2. Each of theinlet 7 and the outlet 9 is a standard garden hose coupling connection,although in the FIGS. the inlet is shown as internally threaded and theoutlet is shown as externally threaded. The outlet 9 is positionedhigher than the inlet 7 in order to insure the desired mixing of liquidsin the outer container 2.

An inner container 11 is formed in the outer container 2. The innercontainer 11 and the outer container 2 have the walls 3 and 5 in commonwith each other. The inner container 11 also has walls 12 and 13 andother walls, not shown in the FIGS. The inner container 11 has an inlet14 in the common wall 5. The inlet 14, which is preferably covered by acap 15, admits a second liquid 16 into the inner container 11. The innercontainer 11 also has an outlet 17 inthe wall 13 for releasing thesecond liquid 16 from said inner container into the outer container 2.

A regulatable valve is provided in the outlet 17 of the inner container11 for controlling the volume of the second liquid 16 released from theinner container 11 into the outer container 2. The outlet 17 comprises avalve seat. The regulatable valve comprises a valve head 18. Apositioning device affixed to the valve head 18 positions said valvehead in the valve seat 17 to a desired extent.

The positioning device of the regulatable valve comprises a rod 19having one end 21 affixed to the valve head 18. The other end 22 of therod 19 is threadedly coupled to an internally threaded control aperture23 formed in the common wall 5. The end 22 of the rod 19 extends outsidethe inner and outer containers 11 and 2. Rotation of te rod 19 about itsaxis 24 moves the valve head 18 correspondingly in axial directions.

A knurled head 25 'is affixed to the end 22 of the rod 19 to facilitatemanual controlof the regulatable valve.

The walls of the outer and inner containers 2 and 1 1 preferablycomprise translucent plastic material to permit observation of theoperation of the regulatable valve. If the walls comprise opaque plasticmaterial, a clear plastic window is provided in the wall adjacent theregulatable valve to permit visual observation thereof.

In FIG. 1 the inlet 7 of the outer container 2 (not shown in FIG. 1) isconnected to a water faucet 26 of a house 27 via a section 28 of gardenhose. A lawn sprinkler 29 is connected to the outlet 9 of the outercontainer 2 via a garden hose 31.

While the invention has been described by means of specific examples andin specific embodiments, I do not wish to be limited thereto, forobvious modifications will occur to those skilled in the art withoutdeparting from the spirit and scope of the invention.
